Application filed January as, 1920. Serial Nb. 354,541.

T 0 all whom it may concern Be it'known that We, Griennns L. GLARK,EDWARD H. P'nnKrNs, and CLAUDE S. WE Mnr'r, citizens of the United"States, residing at Wayland, in the county of Steuben, State of NewYork, have invented a new and useful Valve-Spring Compressor, of whichthe following is a specification.

This invention has reference to improved valve spring lifters, and it isthe primary object of theinvention to provide a Springlifter which willcompress the usual controlling spring, to permit the valve to be readilyand easily removed. I

A further object, of the invention "is to provide a device of a this,character which may be adjusted to] operate on valves of various sizes,the device having means to permit of unlimited adjustment.

A further object. of the invention is to provide a valve springcompressor which may be readily folded into a small compact article topermit the device to be easily carried within the usual tool box.

l/Vith the foregoing and other objects in within the scope of what isclaimed, without departing from the spirit of the invention.

Referring to the drawings Figure 1 illustrates a side elevational viewof a valve spring compressor 0on strncted in accordance with the presentinvention.

Fig- 2 illustrates a side elevational view disclosing the same in itsfolded position.

Fig. 3 illustrates a rear elevational view thereof.

Fig. 4 illustrates a detail view of the connecting links, taken on line44 of Fig. 1, and t Fig. 5 illustrates a fragmental plan view of thelower spring engaging arm.

Referring to the drawing in detail, the body of the device includesopposed arms 5 and 6, each of which is provided with a band 7 adapted toembrace a portion of the opposed arm. to permit of free and easy toprovide a relatively fiat surface 15, which movement, of one arm,longitudinally of the opposed arm.

Each of these arms 5 and dis formed of suitable metal, the side edgesthereof being substantiallysquare so that the squareends of the arms 8and 9 may closely engage the side edges of the'arms 5" andfiin a mannerto prevent lateral displacement, of the arms 8 and 9 with relationto thearms 5 and 6.

Disposed at the outerendof the'arm 8 is a valve engaging finger 10, thelower extremity of which is pointed as at 11 so that the finger 10 mayengage within the usual groove formed in the valves, now in. use,thereby insuring against movement of the finger l0 with relation to itsvalve,,in one direction. p

This valve engaging fingerlO pivoted tothe arm 8 as at 12, a cut outportion 13;" 1 I being provided adjacent the upper edge of the finger10, which cut out portion provides a shoulderto contactwith the pin l i,secured to the arm 8 and extending laterally therefrom, so that thefinger 10 is restricted from moving outwardly from the arms 5 and 6, butpermitted to move to a position overlapping the arm 8, when the deviceis folder. 1

The lower arm 9, which cooperates with the arm 8 for accomplishing thecompressing result, has its outer extremity twisted is slotted as at 16tostraddle a portion of the valve rod, of the valve under operation.

Associated with the arms 8 and 9 are the connecting links 17 and 18.which have one of their respective ends rigidly secured to the bars 8and .9 bymeans of the bolts 19, and as shown, the upper connectinglink17 is pivotally connected to the operating handle 20, as at 21, theoperating handle 20 also being pivotally connected to the operating rod22, by means of the removable pin 23 adapted to be positioned in one ofthe openings 24, provided on the operating rod 22. 'From the foregoingit is obvious that due to the spaced relation of the openings 24, anappreciable adjustment may be had, between the operating rod 22 and theoperat ing handle 20, thus adapting the device for use in connectionwith valves of various sizes.

The lower end of the operating rod 22 has connectionwith the connectinglink 18 by means of the bolt 25, so that movement of the operating rod22 causes a relative movement-of the arm 6, since the bolt 25 passesthrough the arm 6,-to rigidly connect the same with the lever 22.

It might be further stated that the connecting bolt which connectstheoperating lever 20, to the connecting link 17 also 6X-" tends throughthe openingprovided in the arm 5, so that movement of theoperatinghandle 20 causes the arms 5'and 6 to slide {with relation to each other,to bring the arms 8 and 9 toward and away from each other, accordlng tothe direction n which the operating handle 20 is moved.

In the operation of the device, the valve engaglng finger 10 1spositioned on the valve under operation, and the slotted end of theaunt) is positioned to straddle the 'getherQ ltiollows that the coiledspring usually embracing the valve stem, and which has one ofitsextremities contacting with the r pper surface'of the arm9, iscompressed, reliev.--

ing the valve proper of the tension of the coiled. spring.

' arm pivotally connected thereto, a valve engaging finger pivotallyconnected to one of said'horizontally disposed arms, and means forconnecting the arms to permit the same to be moved to a position inparallel relation witheach other. f r

2. In a'valve spring-,liften-apair of opposed arms, means, for slidablyconnecting the-arms, a pair of horizontally disposed arms havingconnection with the opposed arms, a valve engaging finger pivotallysupported by one of said horizontally disposed arms, theoppositehorizontally disposed arm having a slotted portion adapted to embrace avalve stem, and means for moving the first mentioned arms with'relationto each other, V

In testimony that we-claim the foregoing as our own, we have heretoaffixed our signatures in the presenceof two witnesses.
